i know it wont sound great even still but i have no bass what so ever... im not sure if its the wiring or what i read that if its a bit lose the bass can sound rubbish but when connecting to the rear of the stereo i didnt have the metal pins for the end of the wire i just pushed the wire right down into it and secrued it in there with some cardboardcould this be the problem ?
